Green Flexibility commissions 83.4 MWh BESS in Bavaria, Germany

Green Flexibility has invested around €35 ​​million (USD 41 million) in the construction of the battery storage facility with a capacity of 38.5 MW / 83.4 MWh. The plant, which is connected to the grid connection point in Balzhausen, has now been officially commissioned. More than 80 guests from politics, the energy sector, and the surrounding communities attended the event in Balzhausen last week.

The distribution network operator LEW Verteilnetz launched a tender for its “Einspeisesteckdose” or Feed-In Socket. Three battery storage systems, three photovoltaic systems, and a wind farm with a total capacity of 126 MW received grid connection approval. The feed-in socket has a capacity of 80 MW and will be expanded by approximately 60% due to the additional projects. This is made possible by a coordinated and grid-oriented operating mode for the systems, ensuring that the capacity at the grid connection point is not exceeded.

Green Flexibility’s battery storage system is the first of three storage projects to be completed and connected to the grid. “We are delighted that the first system at our feed-in socket is now operational. Battery storage systems are indispensable for the energy system of the future. Especially in Bavarian Swabia, with its high photovoltaic density and strong renewable energy production, they help to use the electricity grid more efficiently,” explained Barbara Plura, Asset Manager at LEW Distribution Network and Project Manager of the “Einspeisesteckdose.”

With this pilot project, the distribution network operator also aims to gather experience on how new perspectives for generation plants and storage facilities can be created at existing grid connection points. “Balzhausen demonstrates that new solutions become possible when network operators, municipalities, landowners, partners, and we as the operator jointly assume responsibility,” said Christoph Lienert, Co-Founder and COO of Green Flexibility. “Such projects don’t arise because everything is easy – but because there’s a willingness to explore new avenues.”

According to Green Flexibility, this project is the largest battery storage facility in Swabia to date. The company plans to commission at least five more storage facilities this year, thus expanding its flexible, grid-supporting storage infrastructure throughout Germany. Four of these projects are planned at the medium-voltage level and will each be battery storage systems with a capacity of 10 MW and 25 MWh.

Green Flexibility also intends to connect the 40 MW / 90 MWh project in Obergünzburg to the high-voltage grid this year, a spokesperson confirmed to pv magazine Germany.
